I personally have no experience, but here is what ChatGPT has to say:  
I’m glad to hear that the Google Drive link was helpful for your airways model project.

To import a 3D model from Slicer into ANSYS Fluent for computational fluid dynamics (CFD) simulations, you typically need to go through several steps to ensure the model is suitable for CFD analysis. Here’s a general process:

1. **Export from 3D Slicer:**

2. **Preparation of the Geometry:**

3. **Mesh Generation:**

4. **Setup in ANSYS Fluent:**

5. **Simulation and Post-processing:**

Remember, CFD simulations are complex and require careful setup and validation. Ensure that your model boundaries reflect the physical system accurately and that you’ve considered the necessary physical phenomena in your simulation.

If you run into any issues specific to the file formats or steps within ANSYS tools, it may be helpful to consult ANSYS documentation, tutorials, or reach out to the ANSYS user community for advice tailored to the exact version of the software you’re using.

Thank you very much for the workflow suggestion.  
For the step 2. For preparation of the Geometry, can STL files be imported into CAD software like Ansys spaceclaim? I use Solidworks and it seems it does not give you a good detailed model. Besides, would you suggest using Solidworks or Ansys spaceclaim?

I have no personal experience with Ansys SpaceClaim or Solidworks -

Maybe [this](https://discourse.slicer.org/t/is-there-a-guide-for-3d-printing-anatomical-structures/34001/2) helps …

Thank you very much! You are very responsive. I am curious if you ever try to export file from Slicer and then import to and CAD software. So far, I see Slicer is just able to convert file into meshing file (STL etc.) but CAD.

No, unfortunately I have not used CAD software with Slicer or 3D printing yet - but have imported STL into Meshmixer (free for Windows).
